ALIMENTaBY-ras'rn Daran.

My present invention relates to alimentary paste driers, and moreparticularly to ian improved drier of the rotary type 1n which thealimentary paste vproducts such as noodles 5 may be continuouslyagitated during the l0 screens. In this type of driers much time isconsumed in placing the material to be dried upon the screens as well asin removing same after it is dried. Driers of this type are moreadaptable to the handling of macaroni, spaghetti or the like than suchproducts as the various kinds of fancy cut noodles which are of shortlengths and must be spread out evenly in order to dry properl lllith theabove objections in mind, I have developed a new drier in which thenoodles or other similar products may be fed into the drier at the topand gradually lowered to an outlet at the bottom of the drier by meansof gravity, and in which the product is continually turned over and overduring its passage through the drier.

The principal object of my invention therefore, is an improved drier ofthe rotary t e.

ylriother object is an improved drier in which the drying material willbe continuously agitated during its progress through the drier.

In the accompanying drawing which is of a more or less diagrammaticform,

Fig. 1 is a central vertical section showing the several rotatablechambers in elevation;

Fig. 2 is a cross section taken on the line 2, 2 of Fig. l.

Referring to the drawing, designates a frame in which are journalledseveral drive shafts 11, 12 and 13, and adapted to support and rotateseveral hexagonal drying chambers 14, 15 and 16 respectively, by meansof chain driven sprockets 17 connected together by chains 18 and 19. y

Power to rotate these chambers is transa mitted to the drier through themedium of the belt 20, which may be driven from any suitable means suchas electric motor or the like.V

At 21 is located an air passage totally in* closing the chambers 14, 15and 16 on all sides except atv top and bottom. Air is f forced throughthis passage to speed up the drying of t-he material within the chambersduring its passage through the drier.

Chambers 14, 15 and 16 Vare built with hexagonal sides comprising aframe work 22 supported internally by members 23 located at each end andat the center. On the inside of these chambers is provided a screen 24having a relatively coarse mesh but close enough to prevent the noodlesor other products from falling through. One end of each chamberissmaller than the other so that the sides will have a downward pitchsufcient to cause the drying material inside the chamber to rotate in adownward direction as thechambers are rotated. At the large end of eachchamber, I have provided openings 26 to allow the drying material withinthe chambers to pass from the chamber through passages 28 in the frame10, to the next succeeding chamber, the small end of each chamber isopen for this purpose.

In operation, the material to be dried is fed into the hopper 30 fromwhich it passes through the end chamber 14 adjacent said hopper and isslowly rolled along through this chamber until it reaches the opening 26in the opposite end from which it drops through the recess 28 in sideframe 10 and so on until it finally emerges at the outlet 32. During thetime the dryingvmat-erial is passing through the chambers, a continuousdraft of air is passing through the drier and by the time the product inthe chambers has reached the outlet 32, it is thoroughly dried.

Having thus described my invention, what I claim as new, is

In a rotary drier for alimentary paste products and th-e like comprisingin combination, two journalled side frames, a series of oppositelyopposed and `vertically disposed rotary drums having hexagonally shapedsides wider at one end than at the other end and attached tohorizontally disposed drive shafts, said drive shafts journalled in saidside frames and progressively driven by -means of chain and sprocketmechanism, the said side frames being recessed at points adjacent th-elarge end of said drums, said recesses extending down to a pointadjacent and above the shaft extending through the small end of one ofthe said drums located below the said irst drum, the large end of thesaid first drum extending in a longitudinal direction beyond the sinallend` of the said sec-l ond drum, the large end of the said first drumbeing provided with openings in its hexagonal sides adjacent said sideframe and enclosed within side frame at all pointsv except at the pointconnecting with the llower r-ecess extension communicating with the saidlower drum, an inlet chamber located in the top of one of the said sideframes communicating with the small end of the topniost drum, an outletin the other side fra-nie directly below and communicating with theopenings in the hexagonal sides of the large end of the lowermost drumlocated within a recess provided in the sa-idside frame, a norina'llyair tight casing separating and supporting saidA side frame surrounding'all of said drums except, at such; portions asy are covered by saidside-frames andfurther provided With inlet and outlet openings locatedon the bottoni. and top respectively of said air tight casing,substantially as shown'and described'.

In witness whereof, I hereby subscribe iny name this 10th day ofJanuary, 1928.

MICHELE CANTELLA.
